A 21-year-old woman presented with a 4-week history of sudden onset vomiting, nausea and anorexia. Questioning revealed that she had a 7-year history of heavy cannabis use (smoking). She did not describe abdominal pain, change in bowel habit, antibiotic use, foreign travel or contact with gastroenteritis. ⋯ A diagnosis of cannabinoid hyperemesis was made and her symptoms resolved after treatment with intravenous fluids, antiemetics and abstinence from cannabis. Since her discharge and abstinence she has had several relapses, each related to cannabis use and each resolving with abstinence. The patient is now seeking cognitive behavioural therapy to achieve permanent abstinence.

A syndrome of hyponatraemia associated with excessive beer drinking was first recognised in 1971. This syndrome has been referred to as beer potomania. Dilutional hyponatraemia occurs due to excessive consumption of an exclusive beer diet which is poor in salt and protein. We report a case of beer potomania who improved dramatically with introduction of solute load, with no subsequent neurological sequelae.

Soon after admission she developed acute urinary retention. ⋯ Cultures from theatre grew Staphylococcus aureus sensitive to flucloxacillin. After 12 weeks of intravenous/oral antibiotics, she was discharged without any neurological disability.

'Legal highs' are recreational drugs sold over the internet and the so-called 'head shops' all over the UK. They are freely available to buy and use as they are not covered by the Misuse of Drugs Act 1971. Mephedrone (4-methylmethcathinone) was sold as a 'legal high' until 17 April 2010 when it was made a class B drug under the Misuse of Drugs Act 1971. ⋯ Not much is known of the effects of mephedrone on mental health. We present a case of dependence and psychosis in a patient using mephedrone (4-methylmethcathinone). The patient needed inpatient hospital care, was treated with antipsychotic olanzapine and recovered well.

Case Reports
Hydroxocobalamin treatment of acute cyanide poisoning with a jewellery-cleaning solution.
Acute cyanide poisoning by ingestion is often severe and lethal among jewellery industry workers. Clinical experience with hydroxocobalamin alone in severe acute cyanide poisoning by ingestion remains limited. This case concerns a 50-year-old goldsmith who tried suicide by ingestion of a jewellery cleaner solution containing approximately 1.2 g of potassium cyanide. ⋯ Following hydroxocobalamin treatment, neurologic and metabolic disorders rapidly improved. He was discharged home 4 days later, without neurological sequelae. The case reinforces the safety and effectiveness of hydroxocobalamin in acute cyanide poisoning by ingestion.
